1 ROOM PRESSURE SOLUTIONS FOR HEALTHCARE FACILITIES UNDERSTANDING, ACCELERATED

2 DESIGN YOUR HEALTHCARE FACILITY WITH CONFIDENCE TSI-Proven Leader For over 20 years, leading healthcare facilities have relied on TSI s PresSura Room Pressure Products for effective, 24/7 monitoring of isolation rooms, operating rooms, and other specialized spaces. Engineers across the globe have made TSI s PresSura Room Pressure Products The Standard for low pressure room monitoring applications. Over 50,000 TSI systems are used every day to ensure safety in leading healthcare facilities. Design your next healthcare facility with confidence when you choose PresSura Room Pressure Products. Safety and Compliance Whether designing or managing healthcare facilities, you understand that safety, compliance and infection prevention are crucial considerations. PresSura Room Pressure Products provide the confidence you need to comply with major industry guidelines and regulations in order to ensure and document safe environments. Specifically designed for hospital applications, PresSura Room Pressure Products offer: + Best-in-class measurement of low pressures to help monitor critical pressurized rooms + Simplified compliance with relevant parts of the following guidelines and regulations: - ANSI/ASHRAE/ASHE Standard , Ventilation of Health Care Facilities - The Facility Guidelines Institute (FGI), 2010 Guidelines for Design and Construction of Health Care Facilities - Centers for Disease Control (CDC), Guidelines for Environmental Infection Control in Health Care Facilities + Seamless integration into Building Automations Systems (BAS) where data can be logged and tracked over long periods of time + Low maintenance and easy calibration 2

3 PRECISION MEASUREMENTS In Hospital Isolation Rooms and Operating Rooms, it s all about safety. And when it comes to safety, you need reliable, accurate measurements for your applications. TSI s unique pressure sensor, based on thermal anemometry, provides the most accurate results at the required 0.01 in. H 2 O (2.5 Pa) used in isolation rooms. HVAC pressure transducers simply can t measure up. TSI Through The Wall Sensor ± 10% of Actual Reading Initial Accuracy Comparison at in. H 2 O Differential Pressure Transducer A ± 0.05 in. H 2 O Range ±0.5% Accuracy Pressure Transducer B ± 0.1 in. H 2 O Range ±0.8% Accuracy ± 10% of Actual Reading ± 15% of Actual Reading ± 18.3% of Actual Reading ± in. H 2 O ± in. H 2 O ± in. H 2 O ± Pa ± Pa ± Pa Typical pressure transducers use a membrane which is far less accurate and is subject to drift. When compared with a stable, accurate TSI Pressure Sensor, drift from a pressure transducer can impact the integrity of pressure readings, bringing into question the longterm safety of specialized rooms in hospitals. Maintaining a pressure transducer s accuracy requires frequent calibrations using expensive, dedicated calibration systems. Accuracy After One to Two Years TSI Through The Wall Sensor ± 10% of Actual Reading Pressure Transducer A ± 0.05 in. H 2 O Range ±0.5% Accuracy Pressure Transducer B ± 0.1 in. H 2 O Range ±0.8% Accuracy True Accuracy of the reading (Total Error X Full Scale) at calibration ± in. H 2 O ± Pa ± in. H 2 O ± Pa ± in. H 2 O ± Pa True Accuracy of the reading at the end of year 1 ± in. H 2 O ± Pa (±10% of Actual Reading) ± in. H 2 O ± Pa (±23.3% of Actual Reading) ± in. H 2 O ± Pa (±22.5% of Actual Reading) True Accuracy of the reading at the end of year 2 ± in. H 2 O ± Pa (±10% of Actual Reading) ± in. H 2 O ± Pa (±31.7% of Actual Reading) ± in. H 2 O ± Pa (±26.7% of Actual Reading) ACCURATE BY DESIGN TSI s bidirectional pressure sensors have been the industry standard for over 20 years with thousands measuring rooms every day. TSI pressure sensors utilize thermal anemometry, the measurement of choice for low air velocities, to measure a small amount of air migrating from one pressure region to another. Air goes through a tube where temperaturecompensated platinum RTD sensors measure the velocity, which is calibrated to a corresponding pressure. As-found data from RTD sensors indicate minimal drift and stable measurements. 3

4 ISOLATION ROOMS Airborne Infection Isolation (AII) Rooms and Protective Environment (PE) Rooms require permanently installed devices to continuously measure and monitor room pressure. PresSura Room Pressure Monitors and Controllers provide the most accurate measurement at the point of interest (0.01 in. H 2 O, 2.5 Pa), and provide a simple visual indication of room status. Multi-Room Monitoring Many AII and PE isolation rooms utilize anterooms for additional protection. A single TSI PresSura Monitor or Controller can accept, label, and display room pressure differential measurements from more than one room, providing a comprehensive solution. Isolation Room Ante Room T One PresSura display unit monitoring isolation room and ante room simultaneously. NURSES STATION MONITOR Depending on the facility layout, it may be difficult for the nursing staff to see the status of all the AII and PE rooms. TSI s Nurses Station Monitor provides a central location to view the room status with audible and visual alarms for up to eight rooms (simultaneously), without using the BAS. In addition, the Nurses Station Monitor can be configured to allow the nursing staff to change the room mode of an individual room. 4

5 OPERATING ROOMS Operating Rooms (OR) have unique environment monitoring and control requirements. TSI s PresSura products meets these demands. Room Pressure: Monitors slight positive pressure (+0.01 in. H 2 O, +2.5 Pa) to keep airborne bacteria and other contaminants out. Air Changes per Hour (ACH): With multiple flow input options, the pressure monitor calculates and provides the ACH rate ensuring proper air quantity is being flushed through the room. Temperature and Relative Humidity (RH): These important parameters need to be monitored during medical procedures. The pressure monitors and controllers accept inputs from both and provide a local indication. Additional Applications + Compounding Pharmacies + Pandemic Preparedness Rooms + Intensive Care Units + Laboratories and Vivariums + Clean Rooms + Burn Units + Bronchoscopy Suites + Laundry areas, Food Prep, Construction 5
